Not even squinting will help you see this image without the help of a microscope. This is the smallest inkjet-printed colour image ever produced, and it’s the same size as a single pixel on a Retina display.

"The eye and an ink jet nozzle have a common problem: they must not be allowed to dry while, simultaneously, they must open," explains Jae Wan Kwon, associate professor in the College of Engineering at the University of Missouri. Kwon, with the help of MU engineering doctoral student Riberet Almieda, solved the…

Some say that printers were sent from hell to make us miserable. We cowtow to a machine's anodyne griping about paper jams and ink levels, and still, after reloading the sheets and replacing the blue cartridge, the obstinate piece of machinery refuses to carry out its orders.

Printers, I think we can agree with some relief, are becoming increasingly irrelevant. Still, plenty of people have the hulking old things plugged in somewhere in their homes, and Mattel's gonna put 'em to use. For printing real (fake) hair extensions for you and your Barbie.

Gaping battlefield flesh wounds that take off more than 4 cm of skin can't heal without aid, so researchers at Wake Forest Institute for Regenerative Medicine created a fantastical system that literally prints skin on demand.

Sometimes it's hard to remember that inkjet printers are good for anything other than ripping you off, but news today from HP's own intellectual property czar may change that: the technology that regulates the precise mixture of pigments down to the last picoliter will soon make home kidney dialysis machines more…

Traumatic Brain Injury (TBI) has become one of the biggest challenges for soldiers returning from Iraq and Afghanistan—shockwaves caused by IEDs and rocket-propelled grenades can cause serious damage that is at times nearly impossible to diagnose. DARPA hopes to change that with a disposable strip being developed by…

This new photo-printer from Casio is one mixed-up gizmo: As well as standard photo-printing functions, it's got a 7-inch touchscreen and a full keyboard. So is it a mini computer with printer aspirations, or a printer with computing aspirations? Hard to say, but it's supposedly able to edit the photos you pop in from…

Trusted Reviews has a big investigation on inkjet printers and inkjet ink, and their year-long study comparing fading between more expensive manufacturer brand vs. the cheaper crappy brand shows that you get what you pay for. Over three months, the differences between the two were negligible, with pages only fading…

I can't say that I have ever been impressed by a printer, but the device they are cooking up at Kyocera could be a first. Their new KJ4 series printhead can churn out up to 200 meters per minute at 600 x 480 dpi, or 150 meters per minute at 600×600 dpi—which equates to about 1000 sheets of A4. After consulting a…

Designer Hung Chih Wang thinks the inkjet printer market has room for an ultra-mobile concept: his "Trak" design is a mini printer that snaps onto the lid of your laptop. Handy for hardcopies on-the-go, it's small enough to be USB powered and even has a detachable print head for easy travel storage. There's no mention…

The Pitch: Kodak's ESP 3 all-in-one printer, which has a nice black finish and a software feature for facial retouching with "one click" that "reduces blemishes" and enhances facial features. They also claim that it saves 50% ink when compared to similar inkjet printers.The Catch: It's hard to tell exactly what the…

Scientists at the University of Tokyo have developed a new 1mm thick plastic sheet inkjet-printed with various nanoparticles and insulating and semiconducting polymers that enables electronic devices placed on it to communicate with one another. A technology like this would have advantages over other means of…

HP has figured out a way to make their inkjet technology a bit more versatile: by getting it to inject drugs into humans. Yep, HP is looking to replace hypodermic needles with their inkjet technology in a method reminiscent of nicotine patches. HP is licensing a patch with up to 90,000 microneedles per square inch…

Epson's latest line of Stylus Pro "Print Engines," better known to us as inkjet printers, have just been announced. The 4880, 7880, 9880 and 11880 all have their share of interesting features, such as the ability to hold a wine bottle's worth of ink in one cartridge.

Remember Kodak's latest multifunction printers? The ones Kodak was all cocky about, claiming that they crushed the competition with amazing photos at 10 cents? Well, according to Popular Photography, it's all a big pile of steaming bull dung.

Just before I'm ready to go to bed, Kodak drops news we hinted at yesterday: Multifunction printers pumping a revolutionary ink through their nozzles that'll create prints with an archival life of 100 years, versus standard inkjet photos that go the way of toilet paper after 15. And the ink costs half the price.…
